- Specification of Letters Patent.

Patented Nov. 11, 1913.

To'all whom t may concern:

NAUDE, a citizen of the United States, resid'- ing at Haverhill, in thecounty of Essex and State of Massachusetts, have -invented anImprovement in Water-Coolers, of which the following is a specification.

This invention relates to that class of Water-coolers in which a sealingand cooling receptacle, or container, is provided Within the body of thecooler, into which water is discharged from an inverted bottle supportedthereover, as the water is drawn from the receptacle. 0 ter, so far as Iam aware, the air which must enter the bottle and ass through the waterIn prior devices of this charactherein, to permit t e water to flowdown,

into the sealing container, is taken directlyv into the containerthrough its top opening, so that dust and otherimpurities, which may becarried by the air, are likely ,to be i taken up by the Water in thebottle'as the air passes up throughgit. As the airusually passes beneaththe cover into the cooling chamber, it comes in contact with the icetherein, so that germs or impurities which may be liberated on themelting of the iceare also likely to be taken up by the air, which laterpasses up through the waterin thebottle. 4

The primary object of my invention is.' to

provide a form of watercooler of the above described type, in which theentrance of air, containing germs or impurities, into the sealing tank,and the subsequent assage thereof through the water in the bott-le, ispreventeds o that a completely sanit-ary'cooler1 .of the abovevtype isproduced. I accomplish this object by the means shown in the accomlpanying drawing, inwhich,

Figure l is a central verticalsectional view of a water-cooler providedwith my invention. Figs. 2 and 3 are det-ailviews in plan and sideelevation, respectively, of the coupling for providing a ti htconnection between the bottle and sealing receptacle,

which I employ. Fig. 4 is a detail sectionalview of the air filter, andFig. 5 is a detail view Showing a modified arrangement of air inlet.

As shown in the drawing, an ice receptacle, or tank a, of usual form,is'provided, said tank having a cover b, provided with a side opening7)', through which the ice is passed to fill the tank, and a centralbottle- Be it known that I, WILLIAM E. PA'I'-,

receiving opening b2.

, A water container c, is arranged within tion with the walls of theneck. An air' filter d is provided in the end of said pipe d, and mayconsist of a layer of absorbent cotton d2, or some similar antisepticmaterial, arranged between screens of fine wire gauze d, although anyform of filter which will purify,'or make antiseptic the air passingtherethrough, may be employed. Means whereby the filter Amay beconveniently renewed are preferably provided.

A closure e, preferably of elastic rubber, is provided, said coverhaving an integral elastic fiange e at its edge, which is adapted to besprung over the fiared end of the neck 0'.of the container, to make atight connection therewith. Said closure is provided with a centralaperture e, which is surrounded by 'an integral, annular, elastic l lipe", depending from the under side of the closure, and a sealing tube fis arranged within the neck c', in register with said aperture, and hasa flanged upper end Which is inclosed by said lip e3 to make a tightconnection therewith. Said tube f is adapted to extend slightly belowthe normal Water level in the container, and a free passage of air isprovided from tube d to the 'surface of the water about said tube f.Said closure is also provided with a combined funnel and coupling e4,-which is integrally connected ithereto at its upper side and surroundsthe aperture e2 therethrough, the upper portion thereof 'extendingthrough the aperture b2.

in the cover b, and having a` turned-over elastic lip e5 at its upperedge, which engages the upwardly extending fianged edge surrounding saidopening b2.

The bott-le g is of usual form and is provided With a neck g having aconical-shaped end portion g2, which is adapted to be forced into thelower end portion of the funnel e4, so as to make an air-tightconnection therewith, the elasticity of the funnel permitting it toyield to some extent as shown in Fig. 1. The parts are so formed withreference to the shapeof the bottle that the top portion of the bottlewill, at the same time, rest on the edge of the rubber covered lip b3,which forms a cushion therefor. f

The container c is provided with the usual outlet pipe which isconnected to the container c, and extends through the wall of the tanka, terminating in a faucet i.

In operation the neck of the bottle is placed 1n the funnel portion e4of the cl'osure, so that the water flows therefrom into the containeruntil the lower end of the sealing tube f is submerged, preventing thefurther passage of air into the bottle. During this operation, and whenwater is drawn from the container, the air which is drawn into thecontainer to permit the displaceyment of the water therein, will bedrawn beneath the cover into the ice-chamber and thence through the airfilter d and pipe d, the entrance of air to the container or bottle, inany other manner, being prevented. It will be apparent, therefore, that,with the apparatus above described, all the air which comes in contactwith the water from the bottle may be previously purified and madeantiseptic.

In'Fig. 5 I show a modified arrangement of the air-inlet pipe, in whichthe air-inlet pipedO is extended upwardly through an aperture in thecover b, so that, instead of taking the air from within the tank, it istaken entirely from outside the tank. For some reasons this arrangementis preferable, as it is believed to be more economical of ice than inthe previously described arrangement, for the reason that the warm airfrom the room is nat carried through the ice chamber in such a way as tobe cooled to such an extent, as with the other arrangement.

I claim 1. A water cooler comprising an ice receptaele having a coverprovided with an opening, a water container arranged in said receptacleand having a top opening, a tubular receiver for the neck of a bottlearranged to connect said openings and having a seat therein to receivethe end portion of the bottle neck to make a tight connection therewith,a sealing tube having a tight connection with said seat and dependinginto said container, and means to admit air to the container about saidsealing tube, substantially as described.

2. A water-cooler comprising a Water container having a top openingaclosure for said opening having an aperture therethrough, a sealing tubeconnected to said closure and depending into the container, an upwardlyextending funnel havin a tight connection with said closure and adaptedto receive the neck of an inverted bottle, to make a tight connectiontherewith, and n means to admit air to the container above the lower endof said tube, substantially as described.

3. A Water-cooler comprising a water container having a top opening, aclosure for said opening having an aperture therethrough, a funnel ofelastic material having a tight connection with said aperture, a sealingtube having a tight connection with the aperture of said closure anddepending into said container, an inverted bottle having its neck seatedin said funnel, and means to admit air to the container about said tube,substantially as described.

4. A water-cooler comprising an ice-receptacle having a cover providedwith a central opening, a water container arranged in said receptacleand having a top opening, a closure forsaid opening having an aperturetherethrough, a funnel of elastic material having a tight connectionwith said aperture and extending through the opening of said cover andsupported by the sides thereof, a sealing tube having a tight connectionwith the aperture of said closure and depending into said container, aninverted bottle hav- Ving its neck seated in said funnel and restingagainst the sides of the cover opening,

`and means to admit air to the container about the sealing tube,substantially as described.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.V
